Javascript Tutorial with Examples For Beginners (pt 1)
 
04:21
This is part one of a series of javascript programming tutorials for beginners. I've created a bunch of example and sample problems for you to solve here: http://www.pyaraapp.com/js-tutorial-1.html Go to that site, open the developer console and type in the following commands and see what happens: /* Javascript Can Change HTML Content */ document.getElementById("demo").innerHTML = "Hello There"; /* JavaScript Can Change HTML Styles (CSS) */ document.getElementById("demo").style.fontSize = "30px"; /* JavaScript Can Hide HTML Elements */ document.getElementById("demo").style.display="none"; /* JavaScript Can Show HTML Elements */ document.getElementById("demo").style.display="block"; The problem with most javascript tutorials is that they don't give you enough example problems. If you are a beginner, it is really hard to learn how to code by just watching videos. You need to go out there and really solve sample problems. What is javascript: JavaScript is the programming language of HTML and the Web. Programming makes computers do what you want them to do. JavaScript is easy to learn. This tutorial series will take you from a JavaScript beginner to an expert. Why Study JavaScript? JavaScript is one of the 3 languages all web developers must learn: 1. HTML to define the content of web pages 2. CSS to specify the layout of web pages 3. JavaScript to program the behavior of web pages This tutorial is about JavaScript, and how JavaScript works with HTML and CSS. Learn by Examples: Examples are better than 1000 words. Examples are often easier to understand than text explanations. This tutorial supplements all explanations with clarifying "Try it Yourself" examples. If you try all the examples, you will learn a lot about JavaScript, in a very short time! In this video, I will use the javascript console thats built into the chrome developer tools to get you to start writing javascript code. With the chrome browser, you will be able to write out some code and see the results immediately. Then I will show you how to store a variable and what a variable really is. Then I will go over the different types of variables and then how to output the values of these variables you created.

JavaScript for getElementById
 
02:34
Introduction JavaScript JavaScript is a scripting or programming language that allows you to implement complex things on web pages — every time a web page does more than just sit there and display static information for you to look at — displaying timely content updates, interactive maps, animated 2D/3D graphics, scrolling video jukeboxes, etc. • HTML is the markup language that we use to structure and give meaning to our web content, for example defining paragraphs, headings, and data tables, or embedding images and videos in the page. • CSS is a language of style rules that we use to apply styling to our HTML content, for example setting background colors and fonts, and laying out our content in multiple columns. • JavaScript is a scripting language that enables you to create dynamically updating content, control multimedia, animate images, and pretty much everything else. (Okay, not everything, but it is amazing what you can achieve with a few lines of JavaScript code.) Before You Starting JavaScript You should know basic HTML and CSS

My Personal JavaScript Notes on How to
 
05:30
MyWebSite: https://www.aimiecaprice.com How to store an HTML elements content into a variable. How to write content to a variable using JavaScript. How to run a comparison statement on an HTML elements content When I initially dove into this, creating the condition was the thing that stumped me most. I got the rest of the equation that stated if this condition exists, do xyz. But my problem came with how do you get JavaScript to check if the condition exist and how do you create condition? Actually creating the condition is what really stump me most probably because I was over thinking it. I knew I wanted JavaScript to change the CSS display property depending on what image a user clicked...so I needed to write a function, make the image clickable, and have the function fire off "OnClick" So I created the condition inside the function which meant every time that function fired off the condition would be created by the function. JavaScript would literally write code that stated var x = 1, or var x = 2, depending on which function was being called by the user clicking various different images. . Example var x = 1; if( x == 1) { document.getElementById("desTxt1").style.display = "inline-block"; document.getElementById("desTxt2").style.display = "none"; document.getElementById("desTxt3").style.display = "none"; document.getElementById("desTxt4").style.display = "none"; document.getElementById("desTxt5").style.display = "none"; document.getElementById("desTxt6").style.display = "none"; document.getElementById("desTxt7").style.display = "none"; document.getElementById("desTxt8").style.display = "none"; document.getElementById("desTxt9").style.display = "none"; document.getElementById("desTxt10").style.display = "none"; document.getElementById("desTxt11").style.display = "none"; document.getElementById("desTxt12").style.display = "none"; }

ASP NET TextBox and JavaScript

Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/03/aspnet-textbox-and-javascript.html In this video we will discuss 1. JavaScript focus method 2. JavaScript select method 3. How to count the number of characters as you type in a textbox and display that count in a label control JavaScript focus method : focus() method is used to put the keyboard cursor in a particular textbox when the web page loads so that we can start typing without having to first click in the textbox with the mouse. For example, when a web page with the following HTML and JavaScript is loaded, the keyboard cursor is already in the textbox waiting for the user to type his input. There is no need for the user to first click in the textbox with his mouse. Name : [asp:TextBox ID="TextBox1" runat="server"][/asp:TextBox] [script type="text/javascript"] document.getElementById("TextBox1").focus(); [/script] focus() method can be used with most HTML elements. For example, when a web page with the following HTML and JavaScript is loaded, the keyboard focus is set to DropDownList1 control. You can change the Gender value in the DropDownList by pressing ALT + Down Arrow keys simultaneously. Since we are using focus() method there is no need to first click on the DropDownList with the mouse. [table style="border:1px solid black"] [tr] [td]Name[/td] [td][asp:TextBox ID="TextBox1" runat="server"][/asp:TextBox][/td] [/tr] [tr] [td]Gender[/td] [td] [asp:DropDownList ID="DropDownList1" runat="server"] [asp:ListItem Text="Male" Value="Male"][/asp:ListItem] [asp:ListItem Text="Female" Value="Female"][/asp:ListItem] [/asp:DropDownList] [/td] [/tr] [/table] [script type="text/javascript"] document.getElementById("DropDownList1").focus(); [/script] JavaScript select method : select() method is used to select the contents of a text field, so when you start typing, the new text that you have typed will automatically replace the existing selected text. You can use select() method with textbox and textarea controls. When a web page with the following HTML and JavaScript is loaded, the text in the textarea element is selected and when you start typing, the new text that you typed will replace the existing selected text. [table style="border:1px solid black"] [tr] [td]Name[/td] [td][asp:TextBox ID="TextBox1" runat="server"][/asp:TextBox][/td] [/tr] [tr] [td]Comments[/td] [td] [asp:TextBox ID="TextBox2" TextMode="MultiLine" runat="server" Text="Type your comments here"][/asp:TextBox] [/td] [/tr] [/table] [script type="text/javascript"] document.getElementById("TextBox2").select(); [/script] How to count the number of characters as you type in a textbox and display the count in a label control Name : [asp:TextBox ID="TextBox1" runat="server" onkeyup="CountCharacters();"] [/asp:TextBox] [asp:Label ID="Label1" runat="server"][/asp:Label] [script type="text/javascript"] function CountCharacters() { document.getElementById("Label1").innerHTML = document.getElementById("TextBox1").value.length + " charactes"; } [/script]

Events in JavaScript
 
17:08
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/01/events-in-javascript.html What is an event An event is a signal from the browser that something has happened. For example, 1. When a user clicks on an HTML element, click event occurs 2. When a user moves the mouse over an HTML element, mouseover event occurs When events occur, we can execute JavaScript code or functions in response to those events. To do this we need to associate JavaScript code or functions to the events. The function that executes in response to an event is called event handler. In JavaScript, there are several ways to associate an event handler to the event 1. Using the attributes of an HTML tag 2. Using DOM object property 3. Using special methods In this video we will discuss associating event handler methods to events using the attributes of HTML tags. In the following example, the code to execute in response to onmouseover & onmouseout events is set directly in the HTML markup. The keyword "this" references the current element. In this example "this" references the button control. [input type="button" value="Click me" id="btn" onmouseover="this.style.background= 'red'; this.style.color = 'yellow'" onmouseout="this.style.background= 'black'; this.style.color = 'white'" /] The above example, can be rewritten as shown below. In this case the code to execute in response to the event is placed inside a function and then the function is associated with the event. [input type="button" value="Click me" id="btn" onmouseover="changeColorOnMouseOver()" onmouseout="changeColorOnMouseOut()" /] [script type="text/javascript"] function changeColorOnMouseOver() { var control = document.getElementById("btn"); control.style.background = 'red'; control.style.color = 'yellow'; } function changeColorOnMouseOut() { var control = document.getElementById("btn"); control.style.background = 'black'; control.style.color = 'white'; } [/script] Events are very useful in real-world applications. For example they can be used to 1. Display confirmation dialog box on submitting a form 2. Form data validation and many more How to show confirmation dialog in JavaScript [input type="submit" value="Submit" id="btn" onclick="return confirmSubmit()" /] [script type="text/javascript"] function confirmSubmit() { if (confirm("Are you sure you want to submit")) { alert("You selected OK"); return true; } else { return false; confirm("You selected cancel"); } } [/script] JavaScript form validation example : In this example, both First Name and Last Name fields are required fields. When you type the first character in any of the textbox, the background colour is automatically changed to green. If you delete all the characters you typed or if you leave the textbox without entering any characters the background colour changes to red indicating the field is required. We made this possible using onkeyup and onblur events. onkeyup occurs when the user releases a key. onblur occurs when an element loses focus. [table] [tr] [td] First Name [/td] [td] [input type="text" id="txtFirstName" onkeyup="validateRequiredField('txtFirstName')" onblur="validateRequiredField('txtFirstName')"/] [/td] [/tr] [tr] [td] Last Name [/td] [td] [input type="text" id="txtLastName" onkeyup="validateRequiredField('txtLastName')" onblur="validateRequiredField('txtLastName')"/] [/td] [/tr] [/table] [script type="text/javascript"] function validateRequiredField(controlId) { var control = document.getElementById(controlId); control.style.color = 'white'; if (control.value == "") { control.style.background = 'red'; } else { control.style.background = 'green'; } } [/script]

jQuery #id selector
 
10:53
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/03/jquery-id-selector.html In this video we will discuss 1. What are jQuery selectors 2. Different selectors in jQuery 3. #id selector in jquery What are jQuery selectors One of the most important concept in jQuery is selectors. jQuery selectors allow you to select and manipulate HTML elements. Different selectors in jQuery jQuery selectors allow you to select html elements in the DOM by 1. Element ID 2. Element Tag Name 3. Element Class Name 4. Element attribute 5. Element Attribute values and many more Id selector in jquery To find an HTML element by ID, use the jQuery #id selector Example : The following example finds button with ID button1 and attaches the click event handler. [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { $('#button1').click(function () { alert('jQuery Tuorial'); }); }); [/script] [/head] [body] [input id="button1" type="button" value="Click Me" /] [/body] [/html] Changes the background colour of the button to yellow $(document).ready(function () { $('#button1').css('background-color', 'yellow'); }); Important points to remember about jQuery #id selector 1. jQuery #id selector uses the JavaScript document.getElementById() function 2. jQuery #id selector is the most efficient among all jQuery selectors. If you know the id of an element that you want to find, then always use the #id selector. 3. HTML element IDs must be unique on the page. jQuery #id selector returns only the first element, if you have 2 or more elements with the same ID. [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { $('#button1').css('background-Color', 'yellow'); }); [/script] [/head] [body] [input id="button1" type="button" value="Click Me" /] [input id="button1" type="button" value="Click Button" /] [/body] [/html] 4. JavaScript's document.getElementById() function throws an error if the element with the given id is not found, where as jQuery #id selector will not throw an error. To check if an element is returned by the #id selector use length property. [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { if ($('#button1').length ] 0) { alert('Element found') } else { alert('Element not found') } }); [/script] [/head] [body] [input id="button1" type="button" value="Click Me" /] [/body] [/html] 5. JavaScript's document.getElementById() and jQuery(#id) selector are not the same. document.getElementById() returns a raw DOM object where as jQuery('#id') selector returns a jQuery object that wraps the DOM object and provides jQuery methods. This is the reason you are able to call jQuery methods like css(), click() on the object returned by jQuery. To get the underlying DOM object from a jQuery object write $('#id')[0] 6. document.getElementById() is faster than jQuery('#id') selector. Use document.getElementById() over jQuery('#id') selector unless you need the extra functionality provided by the jQuery object.
